This is a brand new Lenovo ThinkPad X1 Carbon 45N1073 battery for the 14 inch X1 Carbon 2nd Generation laptops.
This internal battery replaces the original 45N1703 battery for second generation Lenovo ThinkPad X1 Carbon 14" laptops and is used on all Lenovo laptops that begin with type 20A7 or 20A8.
There are currently 3 generations of X1 carbon laptops. To be certain your order the correct battery, your battery part number or model number should match with one from the list below. The battery part number is located on the battery and the model number is located on the laptop.
This laptop was originally announced on Jan 7 2014. You can find your type number on the bottom of your laptop. The type number (or part number) will come right before your laptop's serial number which is abbreviated as S/N.
The laptop case will need to be opened in order to change the battery. This is an easy task if you have a small phillips head screw driver. There are 7 screws that need to be removed to pop off the keyboard cover. The keyboard will come off and expose the battery. The battery has a cable that inserts into the main board. This ribbon cable will be removed and the wiring harness on your new battery will plug into the motherboard in the same opening.
We use the highest quality lithium-ion battery cells and components. Our Lenovo 45N1073 batteries last longer and charge faster than the cheaper, lower quality batteries you see on Amazon and eBay. This laptop battery replacement is 100% compatible with the original battery specifications and is individually tested and backed by a 1 Year warranty.
